Weber 80390 Q300, 320 & Q3200 Propane Manifold

What Problem This Part Solves

The manifold is the central gas control system of a grill. It connects the propane tank to the burner valves and regulates gas flow to each burner. If the manifold becomes clogged, corroded, or develops leaks, the grill may produce uneven flames, low heat, or fail to ignite properly. Replacing the manifold restores safe gas delivery and consistent burner performance.
